Specific embodiment
Below, referring to the drawings, the present invention will be described in detail.Fig. 2 a shows the sebific duct according to made by the present invention
Section.The sebific duct of the present invention is configured to inner glue layer-tempering silk winding layer the-the first outer glue-line-thermally welded sea from downside to upside
Continuous layer-tempering silk winding layer the-the second outer glue-line.Conventional mode is to make the sebific duct with inner glue layer-tempering layer-outer glue-line
Afterwards, it is wound around adhesive tape and is vulcanized, then form thermally welded spongy layer to the outside of outer glue-line, and re-form the second outer glue
Layer.When forming the second outer glue-line, can be wound around together with tempering silk, or can also form one in the downside of the second outer glue-line
Tempering layer.
In order to manufacture the sebific duct of the present invention, sulfur is carried out being wound around adhesive tape by the spiral rubber hose made by conventional method
It is installed on wrapping machine after change.Now, after spiral rubber hose being vulcanized, sponge is adhered to, this is to apply to press
Power simultaneously carries out vulcanizing to release the air being present between hose lining, tempering layer, each layer of outer glue and the rubber of sebific duct, and help
Adhesion between rubber.
The initial adhesion of the outside of the sebific duct so being vulcanized and spongy surface does not carry out thermally welded, thus plays thermally welded
The sponge of bottom surface effect is adhered to using binding agent, and is adhered to the 1/2 about of sponge thickness with thermally welded.
And, can calculate, by calculating the specification of sebific duct and weight, the weight via thing, the buoyancy that sebific duct needs have
And set the thickness of the thermally welded use sponge being used.
Width usually as sponge uses width in 200 to 450mm, but can be according to thickness also to be wrapped in roller
Form is formed, or also can be formed with the form not being wound.
In order to be wound around sponge, in the deflector roll being attached with required width up and down of guide eye portion, the side being wound
To make radiator towards the temperature of the fusing point distributing sponge in the way of sponge, Wrapping formed machine rotates and makes sponge for downside
Deposition.Fig. 6 shows concept map related to this.
In order that sponge deposition, before being wound around sponge, sponge comes off from guide eye, and through guide rolls support radiator,
Easily to carry out deposition.
And, when being wound around sponge, the quantity of spongy layer is preferably even number, and is wound in become with respect to the rotary shaft of sebific duct
45 ° about.If being wound around the spongy layer corresponding with required thickness, after the both-side ends part of smooth sebific duct, it is wound around
Tempering silk (now, outer glue-line can be wound around, and simultaneously wound tempering silk and rubber slab and form the second outer glue-line).
If being formed to the second outer glue-line, and it is wound around binder, then after being vulcanized, untie binder, then complete floating sebific duct.
The floating sebific duct made by this method has higher durability, and not only larger to the resistance of external force, and has
Higher buoyancy, and it is readily adaptable for use in conventional sebific duct.
But, generally, when making sebific duct, if the thickness of sebific duct is too thick or width is too big, it is difficult to process, thus sebific duct
Width and thickness according to the specification of sebific duct depending on.But, floating sebific duct needs there is a certain degree of buoyancy, thus, make
In the case that buoyancy becomes big, the intensity of sebific duct can decline, but in the case of laying stress on the intensity of sebific duct, buoyancy can under
Fall.
The sebific duct of the present invention can be using method as above by sponge (ethene-vinyl acetate EVA, ethylene-
Vinyl acetate) carry out thermally welded, to reduce the thickness of sebific duct.Durability in order to prevent sebific duct to have reduces, and is
Formation sebific duct, can form tempering layer.In the sebific duct of the present invention, independently can only form tempering layer it is also possible to utilize simultaneously
The method being wound around rubber slab and tempering silk, to form the first outer glue-line and the second outer glue-line.
Formation to tempering layer in the sebific duct of the present invention is described in detail.The tempering layer of the present invention is in conventional sebific duct
Form form thermally welded spongy layer it is also possible to be formed as, outside it, there is outer glue-line while form tempering layer it is also possible to
Initially just formed using following method.
Fig. 2 b and Fig. 2 c shows the example forming tempering layer, can use as tempering layer drawn by terylene, nylon, Kev,
The tempering silk that a certain kind in aramid fiber is made is it is also possible to applying tempering silk and using.It is wound around above-mentioned on inner glue layer by continuation
Tempering silk, to form tempering layer, can form multiple tempering layers being wound around tempering silk.Fig. 2 b shows the sebific duct of the present invention
Shape and its section.
The line being used during formation tempering layer is terylene, nylon, Kev draw, aramid fiber, can be as tempering silk, using about
More than 1000 daniers.Preferably, using more than 1000 daniers and below 2000 daniers.And, can also apply
Tempering silk and use.When coating, have the disadvantage that：Carbamide resin is coated on the outside of tempering silk, due to 1000 denier Buddhist nuns
Tempering silk below you is too thin, causes by outside pressure and easily disconnects, when actual fabrication product, 2000 daniers with
On tempering silk too thick, cause and be difficult to winding, and thickness becomes too thick after wrapping.The resin being used during coating is not
It is confined to polyureas, resin makes rubber and the adhesion of tempering silk become easy.
And, the tempering silk being wound being used during operation is twined in the way of so that unsegregated many tempering silks is not turned off
Around the angle that the tempering silk being wound is formed continues to be wound around with 45 ° to 53 ° of angle.If being twined with the angle more than 45 ° to 53 °
Around, then become Tai Mi between tempering silk and tempering silk so that the thickness after being wound around becomes to be too far away between too thick or tempering silk,
Thus reducing the effect of tempering layer.Because above-mentioned angle is less than the angle of maximum license expansion 5%, thus with expansion
Effect is also less.The winding angle being wound around tempering silk can be different according to the quantity of the tempering silk being once wound, but can be
Above-mentioned 45 ° to 53 ° of angle, the quantity of the tempering silk being once wound reduces, and the bigger winding angle of diameter of sebific duct is more
Greatly.
Use the cloth being woven or weaving as the enhancement layer in conventional sebific duct, if using the cloth being woven or weaving,
Then the thickness of layer is no longer thickening, even if being weaved, also can be easily separated lower floor and upper strata, and is easily divided by sharp object
From the woven tram of institute and an organizine, but, as the present invention, if using tempering silk come the outside of spiral rubber hose, and with cloth
The same during formation, distinguish between the cloth on upper strata and the cloth of downside, the cloth of the upper and lower can be no any overlapping in combination,
But, as the present invention, in the case of being wound around with predetermined angular, be wound around itself be a kind of combine, thus with use institute
Different during the cloth of weaving or braiding, stronger adhesion can be produced.And, by tempering silk application of resin, easily to glue
Attached tempering silk and rubber, thus different from the conventional product of difference rubber layer and tempering layer.
Therefore, even if entering sharp foreign body inside sebific duct, also will not be easily via tempering layer.And, to from inside and outside
The resistance of the pressure that portion applies becomes big, and it is overall that the pressure applying from inside and outside is uniformly distributed to sebific duct.And, in order to resistance in height
Pressure, till just starting to be wound into end winding, needs to prevent tempering silk from disconnecting.
It is also possible to consider to be wound around the thin slice being made up of polyethylene or tyre cord in addition to this tempering silk, but,
In the case of using thin slice, need to be wound around a sheet part overlapping so that the thickness of final products is thickening, in order to resistance in
High pressure, needs to be wound in very dense, thus its efficiency declines compared with using tempering silk, causes and has to using more thin
Piece.Therefore, in the case of being wound around using tempering silk, the quantitative change of the line being used few it is possible to make the lower thickness of sebific duct.
In the embodiment of Fig. 1 b, for flange connector, the inner glue layer of end being equivalent to sebific duct places flange, and
It is wound around along radial direction with tempering silk, so that sebific duct is combined with flange, and merely tyre cord is wrapped in outside rubber
Interior, but, in the case of will be according to the application, as shown in Figure 2 c, though do not use above-mentioned tempering silk it is also possible to by flange with
Sebific duct is connected.That is, if from flange one end starting point using circular (Hoop) mode in the state of placing flange on the upside of inner glue layer
Start, and be set to 45～53 ° afterwards in sebific duct part using spiral type (helical) mode, flange portion is using circle over there
Shape mode continues to be wound around tempering silk, even if then not having the connection units such as tempering silk that flange can also be made to combine, in this case, with
Past sebific duct is wound around by tempering silk, solves the problems, such as to be relaxed because of the sticking problem of rubber and tempering silk, and can be thin
Sebific duct shape in the form of conventional sebific duct embodies flange and the one-piece type sleeve pipe sebific duct of rubber tempering silk.
But it is possible to provide and a kind of bearing higher pressure and there is no a shoulder and thinner sebific duct, rather than to conventional
Sebific duct the same and thick and that there is from shoulder to flange inner.
And if, to form inner glue layer by this method, rubber is mutually mixed with tempering silk, resistance in because in sebific duct
The foreign body in portion and the damage that occurs.
In figure 3, although the sebific duct being formed somewhat has shoulder, it is in somewhat thin shape compared with conventional sebific duct
State.
When forming inner glue layer, common dredge rubber pipe can be formed by manual work, but petroleum pipeline sebific duct utilizes extruder
In the way of tubular type, inner glue layer is formed at heart axle.And, common dredge rubber pipe uses abrasion performance rubber, and petroleum pipeline sebific duct makes
Use oil resistivity rubber.
Fig. 3 shows an embodiment of the sebific duct to make by this method.The embodiment of Fig. 3 is not form outer glue
Layer, and formed to the state of tempering layer, blend rubber layer covers above it.In figure, may can be appreciated that tempering silk is formed across
Similar to covering institute's woven reinforcement cloth, but, for the tempering silk of the present invention, persistently rotate sebific duct while being wound around dimension
Hold the tempering silk of required angle, when being wound around reinforcement cloth, the amount of the active force of the regulation applying along radial direction is restricted, thus
Active force can not be continuously applied as being wound around tempering silk, so that fixing flange or tightly pulling enhancement layer, durable to improve
Property.
And, when forming outer glue-line, after forming enhancement layer, as in the past it is also possible to through sulfidation shape
Become outer glue-line, but, when being wound around many tempering silks, can be with the width of the degree having similar to above-mentioned many tempering silks
Raw rubber plate is wound around together and is formed.Fig. 4 a, Fig. 4 b and Fig. 4 c show this device.At this time it is also possible to omit tempering layer, but
